Qn#(b)(4).The customer returned one unit ae05ml autoend05 ml for investigation.Two loose clips that were closed were also returned.The returned sample was visually examined with and without magnification.Visual examination of the returned device revealed that the sample was returned with its trigger partially engaged and with the rotation tab bent.The returned sample appears used as there is biological material present on the device.First, the trigger cycle was completed.Functional inspection was then performed on the returned sample by attempting to engage the trigger using hand pressure.Upon engagement of the trigger, an audible ratchet sound could be heard indicating that the internal ratchet ears are intact.The next clip was unable to load properly as it became stuck in the bent rotation tab.The sample was disassembled to inspect the internal components.The proximal end of the feeder was found bent.The sample was received with 2 clips remaining in the channel, indicating that 13 clips were fired by the end user including the two loose clips returned closed.The bent rotation tab, the clip being stuck in the bent rotation tab and the proximal end of the feeder being bent are indications that the clips were out of position and stacking on one another.The clip stacking could prevent the clips from loading properly into the jaws.It could not be determined exactly how or when the clips came out of position.A non-conformance has been opened to further investigate this issue.The ifu for this product, l06072, was reviewed as a part of this complaint investigation.The ifu for this product states, "mishandling of appliers may result in improper load and/or closure of the ligating clip." the clip stacking could prevent the clips from loading properly into the jaws.It could not be determined exactly how or when the clips came out of position.A non-conformance has been opened to further investigate this issue.The reported complaint of "clips loaded misaligned" was confirmed based upon the sample received.One device was returned with its trigger partially engaged and with the rotation tab bent.Upon functional inspection, the next clip was unable to load properly as it became stuck in the bent rotation tab.The sample was disassembled to inspect the internal components.The proximal end of the feeder was found bent.The sample was received with 2 clips remaining in the channel, indicating that 13 clips were fired by the end user including the two loose clips returned closed.The bent rotation tab, the clip being stuck in the bent rotation tab and the proximal end of the feeder being bent are indications that the clips were out of position and stacking on one another.The clip stacking could prevent the clips from loading properly into the jaws.It could not be determined exactly how or when the clips came out of position.A non-conformance has been opened to further investigate this issue.
